Abstract
An air filter element includes a first end and a second end located opposite to the first end in relation to a longitudinal direction of the air filter element. The air filter element is configured for axial insertion into a filter housing with the first end leading the axial insertion. The air filter element includes a gripping structure at the second end, the gripping structure comprising an external surface accessible for interaction by a tool to facilitate removal of the air filter element from the filter housing. The gripping structure is also configured to, during insertion of the air filter element into the filter housing, radially align the air filter element in the filter housing.
Claims25
An air filter system, comprising:
- an air filter element having a first end and a second end located opposite to the first end in relation to a longitudinal direction of the air filter element, the air filter element being configured for axial insertion into a filter housing with the first end leading the axial insertion;
- a gripping structure at said second end, said gripping structure comprising an external surface specifically shaped and dimensioned for engagement with a tool to facilitate removal of the air filter element from the filter housing and including guide features configured to mate with corresponding guiding features of the filter housing to radially align the air filter element in the filter housing during insertion of the air filter element into the filter housing;
- a first end panel at the first end of the air filter element;
- a second end panel at the second end of the air filter element;
- a first outlet located in the first end panel and being configured to communicate with a corresponding first housing outlet in the filter housing;
- a second outlet located in the second end panel and being configured to communicate with a corresponding second housing outlet in the filter housing, wherein the gripping structure is integrated into the second end panel;
- a filter housing having an inner housing space being adapted for axial insertion and removal of the air filter element into/from the inner housing space, the filter housing having a first housing end arranged adjacent to the first end of the air filter element when housed in said inner housing space, and a second housing end located distant to the first housing end in relation to a longitudinal direction of the filter housing, the second housing end being arranged adjacent to the second end of the filter element when housed in said inner housing space, wherein the filter housing comprises a guiding structure at the second housing end configured to mate with the gripping structure of the air filter element to radially align the air filter element in the filter housing during insertion of the air filter element into the filter housing and to align the second outlet of the filter element with the second housing outlet, the guiding structure is a guiding indentation arranged at the annular edge of the second housing end.
